Referer checking will not stop open redirects you must create a whitelist. Consider the following

http://site/script?u=http://site/script?u=http://cnn.com

It will hit the script, redirect back to itself set the referer header then continue.

Hello Aditya,
I see your point there. Hope they get it fixed. Should the patch involve
some referrer checking?

Hello there,
I've read the article, but I still do not see where the severe
redirection
vulnerability is. Is this not a feature of the neworder.box.sk web site
to
allow anyone to be redirected to anypage they submit to redirect.php?

Thanks,

RedirectionVulnerability



Hi

Previous Rootkit.com Vulnerability have been patched.
The neworder.box.sk is famous security website.It inherits very
specific
redirection attacks. The domain forwarding or URL forwarding not only
directly possible through the website but can be called from third
party
directly.

A very generic analysis have been undertaken based on search engine
specification.Look into the issues at:

Hi nikolay

                       Thats where the thinking is bit off side.
Remember there
is lot of difference between redirection occurs from the main website
through generating event and the redirection  that occurs from the third
party.It will be okay to the feature context if the redirection supports
only from the website.

More precisely a search engine check is performed at the top to show
that the page is not subjected as standard page for redirection. If its
a feature than it must not be redirected from the third party.

Thats All.

Regards
Adi
